processEnergyUsage

fndouble processEnergyUsage(int pid, Duration window)

Estimates energy usage for a specific process.

This function provides an estimate of energy consumed by a process over the specified time window. This is an approximation based on CPU usage and system power characteristics.

Parameters

`pid`	Process ID to analyze.
`window`	Time window for energy calculation (not currently used).

Returns

Estimated energy consumption in joules. Returns 0.0 if unable

to calculate or process doesn't exist.

Example:

auto energy = processEnergyUsage(1234, 5.seconds);
writeln("Process consumed ", energy, " joules");
